What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Sternglas Marus

The Sternglas Marus is widely praised for its well-built, heavy feel and excellent bezel action, considered the best in its price range. Despite its 42mm diameter and 52mm lug-to-lug, owners report it fits surprisingly well on slim wrists. A reviewer notes the short seconds hand as a drawback, but highlights the watch as a fun, affordable starting point for a collection, featuring a vibrant Pepsi bezel and an anthracite dial that shifts in appearance, powered by a Miyota 8215 movement for €399. Overall, owners and reviewers rate the Sternglas Marus highly for its robust build and superior bezel at its price point.

Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's Watch

The Seiko Prospex Marinemaster 1965 Heritage Diver's Watch is praised for its faithful re-creation of the 62MAS design, with reviewers noting improved wearability due to smaller case sizes (38mm to 40mm) and updated bracelets. Specific models feature a stainless steel case with super-hard coating, ceramic bezel, and a tool-free extension system on the bracelet. Accuracy figures vary, with one model rated at -5/+10 seconds per day and another at -10/+15 seconds per day, powered by movements like the Caliber 8L45 or 6L37 offering 72-hour or 46-hour power reserves respectively. Some reviewers point out drawbacks such as an unsigned winding crown, a lack of tool-free micro-adjust on the clasp for certain models, and a secondary GMT function on one variant. The price point, ranging from $2,800 to $3,600, is considered high by some, especially when compared to other Seiko or Grand Seiko offerings.
